Abstract
The invention is a high capacitance capacitor anode manufactured by creating a green anode body from particles of a dielectric oxide film-forming electrical conducting non-agglomerated powder, sintering the green anode body, and anodizing the sintered body. The non-agglomerated powder comprises fine particles having a small average particle size and a narrow size distribution, which gives the green anode body a morphology that allows it to be sintered at temperatures lower than 1200° C. The invention is also a method of manufacturing these anodes.
